These soft, spiced Eggnog Cookies are a festive delight. Topped with a creamy eggnog frosting, they offer a sweet and seasonal treat that's perfect for celebrating the holidays.
Preheat the oven to 350°F (175°C). Line baking sheets with parchment paper.
In the bowl of a stand mixer, cream together the butter, granulated sugar, and brown sugar until smooth and well combined.
Incorporate the egg, vanilla extract, and eggnog, ensuring a thorough blend.
Gradually add the flour, cornstarch, baking powder, baking soda, cinnamon, and salt. Mix until just combined. Scrape down the sides of the bowl and blend briefly to ensure uniformity.
Using a tablespoon or small ice cream scoop, portion out dough balls approximately the size of a ping-pong ball and place them on the prepared baking sheets.
Place in the oven you've preheated and let it bake for around 10 minutes.
Upon removing from the oven, gently flatten each cookie using a flat-bottomed cup. Let them fully cool before adding the frosting
Frosting Preparation
For the frosting: In a clean stand mixer bowl, blend together the butter, salt, vanilla extract, and confectioners' sugar on low speed until combined. Increase to medium speed and mix for an additional minute.
Gradually add the eggnog, one tablespoon at a time, mixing well after each addition. Continue to mix on medium-high speed for an additional minute until the frosting achieves a fluffy consistency.
Transfer the frosting to a piping bag equipped with a large star nozzle.
Assembling the Cookies
Once the cookies are completely cooled, pipe a spiral of frosting on each cookie, starting from the center and moving outwards. Repeat for all cookies.
Optionally, garnish with a sprinkle of nutmeg or cinnamon.
